The objective of the present test case is to analyze the field resulting from a 3D shock wave /boundary layer interaction occurring in a 3D channel with a swept bump. In this case, the interactions taking place with the boundary layers of the four walls can lead to the formation of several separations which are at the origin of vortical structures cause of intense secondary flows.

Participants are expected to perform grid refinement studies or hp-adaptive computations using a RANS model of choice.  The target quantities of interest are the static pressure distribution on the walls, the turbulent kinetic energy profiles and the mean stream-wise velocity profiles in longitudinal planes. Meshes will be provided at request.

Features and challenges: 
Curved geometry
Steady flow
Transonic flow
Turbulent flow
Reynolds Averaged Navier Stokes (RANS)
